MIXING DEVICE FOR INTERN .AL-COMBUSTION ENGINES.

Application filed January 31, 1921.

To all whom it may concern:

Be it known that I, HAROLD C. citizen of the United States, residing at Shreveport, in the parish of Caddo and State of Louisiana, have invented a. new and useful Mixing Device for Internal-Combustion Engines, of which the following is a specificatipn.

This invention relates to mixers designed for use in connection with internal combustion engines for breaking up the incoming gas to insure a rich mixture.

A further object of the invention is provide a device of POTTER, a

to this character which may be positioned within the intake manifold of an engine, at a point between the carbureter and enginecylinders so that the device will contact with the gas whenthe same has left the carbureter.

A still further object of the invention is to provide a mixer of a novel constructlon, whereby the same will be held within the intake manifold by frictional contact with the inner walls thereof, thereby eliminating within the scope of the use of bolts and other securing means.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it bemg understood that changes in the precise embodiment of the invention herein disclosed, may be made departing from the spirit of the invention. Referring to the drawing Figure 1 illustrates a side -elevat1onal new a blank of which the mixer is formed. Fig. 2 illustrates a side elevational view of the same, showing the fingers as twisted.

Fig. 3 illustrates a sectional view through the blank after the samehas been bent to be positioned within a manifold, the relatively short fingers being shown as removed.

Fig. 4 illustrates a sectional View through the mixer showing the relation of the relatively short fingers with each other, the larger fingers having been removed.

Fig. 5 illustrates a sectional view ing the relation of the short fin the longfingers, certain fingers moved.

Fig. 6'illustrates a sectional view through a manifold showing the mixer as supported therein.

whatis claimed, without Patented N 0v. 8, 1921. Serial No. 441,299.

Referring to the drawing in detail, the reference character 5 designates the bod portion of the mixer, which is formed preferably of spring steel, portions thereof be ing cut away to provide a plurality of relatively short fingers 6, the upper ends thereof being out at angles as indicated at 7, so that a space will be formed between the adjacent finger ends when the body portion is bent in it iraamner to be positioned within the mani- Disposed between the relatively short fingers 6 are the longer fingers -8 which are supported in spaced relation with the relatively short fingers and have their free ends cut at angles as at 9, thereby providing an opening at the adjacent ends of the fingers.

As shown,'by Fig. 2 of the drawing, the fingers 6 are twisted to insure the gas passmg over the fingers taking a spiral course and imparting a swirling motion to the gas to cause'the particles of oil forming a part of the mixture to be broken up into a fine spray.

The relatively long fingers 8 are also convoluted to give the charge a swirling motion, it being understood that the gas passes from the relatively short fingers 6, to the longer fingers 8 on its passage to the cylinders of the engine. r

'As before stated, the body portion 5 is formed preferably of spring steel, so that when the device is positioned within a manifold of an engine, the spring steel will expand and cause a frictional engagement with the inner walls of the manifold, to the end that the device will be secured therein, and prevented from moving with respect thereto.

It is obvious that when the body portion 5 is bent to conform to the curvature of a manifold, the free ends of the relatively long fingers 8 move into close proximity to each other and provide a suitable opening to allow the gas to pass therethrough, while the relatively short fingers 6 have the free ends thereof in close proximity at points between the relatively large fingers, to insure the mixture contacting with the relatively short fingers on its passage through the mixture.

In view of the foregoing description, it

sary.

Having thus described the invention, their free ends disposed in close proximity what is claimed as new'is:-

1. In a mixing device, a body portion formed of flexible material, said body portion adapted to be bent so that the ends thereof will overlap, the body portion adapted to frictionally engage the walls of a manifold pipe, and convoluted fingers forming a part of the body portion and adapted to be moved into close proximity with each other. 7

2. In a mixing device, in combination with an intake manifold, a body portion of flexible material and adapted to be bent to conform to the curvature of said flexible material adapted to expand to frictionally engage the walls of the manifold, and convoluted fingers extending from one edge of the body portion and having the manifold, i

-' with each other.

3. In a mixing device, a body portion, a plurality of relatively short fingers extending from the body portion, relatively-long fingers disposed between the first mentioned fingers and supported in spaced relation therewith, the free ends of the fingers being.

cut at angles, and said fingers adapted to lie in close proximity with each other when the device is positioned.

In testimony that I claim theforegoing as my own, I have hereto afiixed my signature in the presence of two witnesses.
